3 days on pharm for the USMLE 1 is plenty. 2 weeks is overkill and it will only end up hurting you as you push out all of the other stuff you worked hard on learning and replace it with usless pharm facts.
First Aid is the bomb. Lange roadmap looks sweet. I used Micro made Rid Simp for the abx section, thats the reason I still remember my abx to this day. Pharm recall, I used it the whole year for class and was familiar with it. However it is a bit too detailed in many parts for USMLE. As I recall, pharm was extremely light on my version of the exam.
